When I upgraded server from 1.7.4 to 1.7.5, people playing on windows (1.7.5) clients started reporting extreme lag, and server CPU usage goes up by almost 50% of CPU per windows client connected. Other (Linux, OSX) clients do not suffer any lag, and contribute only ~10% of CPU usage per client. For the time being I reverted the server back to 1.7.4, which does not suffer from this issue.

It's not that, as I tested this also in-house on my 3.2GHz quad core, 8GB RAM, ATI HD5870 Windows XP 64bit machine. The biggest concern for me is the abnormally high server CPU usage per windows client connected, which was observed no matter the connection speed or client computer's performance.
Please update your Java to the latest (supported) version and try again.
Also, that kernel is more than two years old. I'm assuming you're on a debian based distro, is there anyway you can get on a more current version?
Vid Vidmar I have something to tell you it is that probably its just the fact that there probably using slow windows computers or something but I use OSX with 4 ram memory chips.
